A Swiss guard walks passed St Peter's Basilica after Pope Benedict XVI's audience to the group renewal in the spirit on May 26, 2012. Vatican police arrested a man the day before, reportedly the pope's butler, on allegations of having leaked confidential documents and letters from the pontiff's private study to newspapers. The man was caught in possession of secret documents, the Vatican said, but it would not confirm the suspect's identity, age, or when he had been arrested. AFP PHOTO/ TOPSHOTS/ FILIPPO MONTEFORTE
